Combination with fertilizers

Materials used in this chapter were published in the book: Biostimulant Albit
for increasing yields and protection of agricultures against diseases, A.K. Zlotnikov,

High agricultural efficiency might be obtained with joint application of
Albit with fertilizers and means of leaf feeding
(foliar liquid fertilizers).

Firstly, Albit increases the utilization efficiency of fertilizers.
Albit increases the coefficient of removal of nutrients from fertilizers
(efficiency of use of mineral fertilizers by plants). In field trials carried
out by Department of Agrochemistry of Moscow State University on spring barley
and wheat, Albit was used in combination with various mineral
soil applied fertilizers (according to standard regulation). In result, it was found that under
conditions of averagely cultivated soil Albit is able to replace up to 18.7
kg/hectare of a.i. nitrogen (N2O5) and 14.2 kg/hectare
of phosphorus (P2O5).

In other words, this corresponds to:

49 kg/hectare of ammonium nitrate,

40 kg/hectare of urea,

65 kg/hectare of superphosphate,

39 kg/hectare of triple superphosphate.

Thus, application of Albit over one hectare makes possible reduction
of mineral fertilizers application approximatelly by 10-30 % of
normal rates without losses of their efficiency.

Results of vegetative trials conducted in Department of Agrochemistry (Moscow
State University), were subsequently confirmed by results of many conducted
field trials (Table 1). For example, in field trial of State Stende
Cereals Breeding Institute (Latvia, 2010-2011) full dosage of fertilizers (N5P20K26 300 kg/ha) delivered the yield of winter wheat of 72.7 c/ha. 15% reduced dosage
of fertilizers together with Albit gave 74.8 c/ha, that brought high economical
outcome (Table 1).

Consumption of fertilizers may be reduced
by 10-30% (nitrogen fertilizers – by 14-21
kg of a.i./hа,
phosphorus fertilizers – by 9-15 kg of a.i./hа)

Addition of Albit (1 ml/10 L) to solution of fertilisers used for watering
of greenhouse and field-grown vegetables established a good reputation in agricultural
practice of vegetable growing farms of Krasnodar krai, Saratov
and Moscow oblasts. In this case, Albit not only increases efficiency of fertilizers,
but also immunizes plants against diseases.

Secondly, mineral fertilizers (basically urea)
are used sometimes for leaf feeding during vegetation period.
Application of urea on wheat provides both supplying of plants with additional
nitrogen for yield formation and increased gluten content in seeds. To increase
winter wheat grain quality, leaf feeding with urea (30-40 kg of active ingredient
per 1 hectare applied through spraying) in EC stages 50-69 is generally used.
Application of such rates requires concentration of urea in working solution
of 10-15%, or even 30% in case of aerial application. However, it is known
that urea concentrations over 1% cause plant burns. Usage of effective antistressor,
such as Albit, can solve this problem. Joint application of Albit with urea
provides full relieve of stress effect of urea fertilizing. All this urea-relating
information can be used in cases of leaf feeding with ammonium nitrate, with
mixture of urea and ammonium nitrate and with other means of leaf feeding.

Albit has been successfully used in combination with urea (leaf feeding in
vegetation period) in practice of farms of Rostov, Tambov, Voronezh and Oryol
oblasts of Russia over several years. Also, high efficiency of three-component
solution of urea, Albit and insecticide has been demonstrated.
